be fully described in the subjoined specification and particularlypointed out 1n the following claims, 4

F i ure 1 is a right-hand side elevation of a su cient portion of a waring machine to be understood with one emhbdiment of my present inventionapplied thereto; F ig.2 is

a horizontal sectional detail on 'the line'22, t

Fig. 1; Fig. 3 is a side view of the balance 7 wheel forming a part ofthe governing o5 means,with some of the adjacent parts; Fig.

4 is anopposite side view, showing the friction connection between thebalance wheel and its actuating shaft; Fig. 5 is a vertical sectionaldetail on the line 5 ,5, Fig. 2, look ing toward the balance wheel.

In Fig. 1, the drivin shaft 1 is provided with the usual fast an loosepulleys, indicated at 2, and in practice there are usually for differentspeeds, the 76 belt being shifted by a suitable belt-shifter or fork 3part1 broken out, these parts formingno nove part of the presentinvention. 'A pinion 4 fast on the driving shaft meshes with anintermediate gear 5. mount- 80 edon the side frame 6 of the apparatus,said gear in turn meshing with and driving a pinion? fast onatransmittin shaft 8 extended across the frame at t e back, the

mechanism for acting upon the threads to draw them from the creel-frame(not shown) andt-o wind them onto a beam'be- 'ing actuated from thetransmitting shaft 8'.

None of this mechanism forms any part of my invention herein and forthat reason it isnot illustrated, as it is old and of .well knownconstruction and operation. From the above description it will be readilunderstood that if the beltis thrown onto t e loose pulley the, shafts 1and 8 and the draft mechanism actuated thereby, will stop quickly, if nomeans be provided to bring such parts to a gradual stop. I have providedsuch means and willnow describe one practical embodiment thereof.

. Upon the shaft 8 at anyconvenient location, I key or otherwise fixedlysecure a' ratchet 9 and a radial arm 10, and interpose between suchparts the hub 11 of a heavy balance whee1'12, the hub-bein mounted torotate upon the shaft. The h u is embraced by a-suita'ble frictioncoupling, shown best in Figs. 4: and 5 as oppositely curved arms 13pivoted on the arm 10 at 14 and embracing the hub, the concave parts of.saidamns being no I faced with leather or other suitable material, andsaid arms are setup as tightly as ma. be necessar by the" clampingdevice 15. Thus I provi ea friction connection or coupling between thetransmittin shaft 8 and the balance wheel 12, so that w en'power isthrown on to the machine the balance wheel will be rotated inthedirection of arrow16, Figs. land '3, solely by-or through theoperation of the balance whee I mount suitable springressed pawls 17which cooperate with t e' ratchet 9, it being remembered that the latteris fast on shaft 8; The pawls and ratchet are so arranged that theycooperate when the balance wheel has attained its normal speed after thepower has been I I and the mechanism actuated by it will be kept inmotion, but 'with a gradually decreasm speed, until the energy' of thebalance w ee is dissipated and t e entire apparatus comes to rest.Consequently the parts of the machine which act upon the warp threadsand pull them along slow down gradually and come to rest with thethreads tight enough to prevent the forma-' tion of kinks, because thegradual decrease in the speed of the draft permits the spools to slowdown gradually, so that they will not overrun and slacken the threads.From the foregoing description, taken w1th -the drawin it will be clearthat in starting up and uring normal 0 eration of the machine thetransmitting s aft 8 and the various mechanisms actuated therefrom arepositively driven and controlled, but, when the power isthrown off, saidshaft 8 and the mechanisms actuated therefrom will be controlled by thegoverning means and gradually slowed down by the momentum of the balancewheel. Thus by a simple and effective formof momentum governor I am'enabled to obviate the objections pointed out 5 at the beginning-of thisspecification, and

of the friction couplin On the outer side without in any way interferingwith the proper normal operation of the apparatus as a whole.

When the apparatus is started u it is immaterial that the balance wheelsips on the shaft 8 and lags behind, for said wheel has no function toperform at such time.

The friction connection or coupling is set up only enough to im artgraduall the re- .5 quired speed to the alance whee, as the shaft, abalance wheel, a friction eou ling function of'said connection orcouplin ex tends no further than to put the 'ba ance -wheel in motionand keep it moving while the ower is on the machme.

arious changes or modifications may be made by those skilled in the artwithoutdeparting from the s irit and 500 e of my invention as set'fort'iin the claims annexed hereto.'- J

Havin fully described my invention, what I c aim as new and desire tosecure by Letters Patent is 1. In apparatus of the class described, atransmittlng member, and normally inactive governing means, including amomentum member rictionally connected with and rotated by thetransmitting member when the latter is power driven, to assume controlof the transmitting member positively and automatically when the poweris thrown ofi and to effect the rotation of said transmit: ting memberat a gradually decreasing speed.
